RAIN-WATER CUT-OFF AND SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 629,988, dated August 1, 1899. Application filed January 23, 1899. Serial No. 703,027. (No model.)

To all whom itrnayboncern: I

Be it known that I, PETER D,-EVANS, a citi zen of the United Statesp'esiding at Dayton, in the county. of illon'tgomery and. State of Ohio, have invented certain new and useful Improvements in Rain-'WaterCut-Olfs and Separators; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the figures and letters of reference marked thereon, whichform a part of this specification;

This invention relates to improvements in rain-water cut-offs and separators.

The object of the invention is to provide a rain-water cut-off through which the water is allowed to pass to the waste for a sufficient length of time for the roof and eaves-troughs to be cleansed of dirt, trash, &c., and after which the water is allowed to pass to the cistern free from such dirt, trash, &c.

In the accompanying drawings, Figure 1 is: a front elevationof. myimproved rainwater cut-oft and separator, the front of the 'casing being removed. Fig. 2 is a side elevation with one side of said casing removed. Fig. 3 is an end elevation of the separating-cylindeu.

Figs. at and 5 are elevations of opposite sides of the separating-cylinder; Fig. 6 is a sectional view through the bottom of one of the Fig. 7 is an elevation of the inner side of one of the brackets or cross-arms. Fig. Sis a transverse section of the separating-cylinder.

The casing 1 may be varied in shape. As shown in the drawings, it, is an upright box on two wide feet 2 2, which rest upon the ground and provide a suitable space for connecting the cistern-pipe (not shown) with the spout 3 and the waste-pipe (not shown) with the spout i. These two spouts communicate with compartments 5 and 6, which are separated by a partition-wall 7. The pipe 8, leading from the eaves-trough, (not shown,) instead of extending down into the ground in the usual manner connects by means of an elbow with a horizontal pipe 9, that runs through the upper end of the casing. This pipe 9 also runsthrough and supports an u pper vessel 10. The lower half of said pipe the mouth of a lower vessel 17 opening 14 is in extent about one-half the area of the end of said cylinder, as shown in Fig. 3, in order to permit said cylinder to turn in a manner and. fora purpose hereinafter described. The lower end of the upper vessel 10 is concaved or tapers to a point and has an openingsurrounded on the lower side by a nipple 15. Screwed into this nipple is a cone-shaped spout 16, projecting down into The bottom of this latter vessel is substantially the same in construction as the bottom of the upper vessel 10 and has a cone-shaped spout 18, secured in a manner similar to spout 16. The opening, however, in the bottom of vessel 17 is somewhat smaller than the opening in the vessel 10 in order that-more water may pass into the lower vessel than can pass out of it through spout lS.

The lower vessel 17 is supported on crossarms 19 19 by chains 20 20, which are attached to the upper portions of the front ends of said arms. The arms 19 19 are fixed to a transverse bar or shaft 21, which has its ends loosely mounted in bearing-pieces 22, secured to the sides of the casing. The arms and bar are limited in their rocking or tilting movementby chains 23 23, secured to the rear ends of said arms and to the back of the casing. Thechains are held out in proper positions by resting against the rounded surfaces on a.

openings in the upper ends of the spouts The consequence is no water is per should be somewhat larger than the openings in the vessels. 24 is a gravity-weight attached to the rear end of one of said arms by a chain 24 The separating-cylinder 13, through which the dirt and accumulations on the roof and in the eaves-troughs are separated from the water, is provided with a shaft 25, which is journaled in the casing. On the shaft 25 there is a fixed pulley 27, to which is secured a chain 27, the ends of which are secured to the inner and outer ends of one of the cross arms 19, so that when the arms 19 19 are tilted in either direction a corresponding movement will be imparted to the separating-cylinder. This cylinder has an unobstructed opening 28' on one side, and on the other side, directly opposite, a similar discharge-opening is closed by a wire mesh 29. On one side of each of these discharge-openings 28 and 29 there is a longitudinal flange 30, which. is joined by semicircular end flanges 31 31. Whenthe cylinder is turned in either direction to its limit, the one or the other of the flanges 30 30 will come against the partitionwall 7 and will enable the entire water entering through pipe 12 to pass to one or the other compartments 5 or 6 and out through the respective outlets therefrom. The weight 24 normally maintains the cylinder in a position to discharge through the unobstructed opening 28 into the waste-compartment 5, through which the water passes for a sufficient time to clean the roof and gutters. The clear water passing in the meantime into the upper vessel 10 through the wire mesh 1]. is passing into the lower vessel 17 and from thence at a slower rate into the separating-cylinder and out with the waste water. WVh'en the lower vessel 17 becomes nearly full of water, the weight thereof exceedsthat of the gravityweight 24:, the arms 19 19 are tilted outward, and the position of the separating-cylinder is reversed from the position shown in Fig. 2. This brings the said cylinder to a position to discharge into the clear-water compartment 6 through the wire mesh 29, which it continues to do while the rain lasts.

The period of time for the water to discharge through the waste-outlet may of course be regulated by varying the sizes of the vessels 10 and 17 and the discharge-openings in the bottoms thereof. When the Water entering the lower vessel 17 passes out to an extent to permit the weight 24E to overbalance it, the said weight places the separating-cylinder in a position for the next rainfall.

Having described myjnvention, I claim- 1. In a rain-watercut-ofi and separator, the combination with a casing, a pipe connected with the eaves-trough pipe, passing through the upper portion of the casing, and entering the lower end of said casing, the portion of said pipe lying within the casing having an opening in the lower side thereof, covered with wire meshing, of a separating-cylinder into which the said pipe discharges, the said cylinder having an unobstructed opening on one side adapted to discharge into the wastepipe, and an opening on the opposite side covered with wire meshing and adapted to discharge into the cistern-pipe, and means for changing the positions of said cylinder, substantially as and for the purposes specified.

2. In a rain-Water cut-ofi and separator, the combination with a casing, and a pipe projected through the upper portion thereof, the said pipe continuing down on the side of said casin g, and projected into the lower end thereof, of a separating-cylinder into which the lower end of said pipe projects, the said cylinder having an unobstructed opening on one side, and an opening in the other side inclosed by a wire mesh, cross-arms, a connection between said cross-arms and the separatingcylinder, a gravity-weight connected to said arms and adapted to maintain the said cylinder in a position to discharge through the unobstructed opening therein, and a water vessel connected to said arms and adapted to maintain said cylinder in a position to discharge through the wire mesh into the cistern-pipe, and means for admitting water to said vessel until the weight thereof overcomes the weight of the gravity-weight, substantially as described.

3. In a rain-water cut-off and separator, the combination with a casing, and a pipe leading from the eaves-trough, of a down-pipe extending through the upper portion of said casing, and down on one side thereof, and projected into the lower end of said casing, the said pipe being connected on the opposite side of the casing to the eaves-trough pipe, and having an opening in the lower side of the portion that passes through the upper portion of the casing, the said opening being covered with a wire mesh, a vessel into which water discharges through said wire mesh while the bulk of said water passes down through said pipe, a lower vessel into which said upper vessel discharges in diminished quantities, a separating-cylinder into which the down-pipe, and lower vessel discharges, the said lower vessel discharging into said cylinder in less quantity than said lower vessel receives from the upper vessel, and means for changing said separating-cylinder to positions to discharge into the cistern, or into the waste-pipe, substantially as herein shown and described.

4. In a rain-water cut-off and separator, the combination with a casing, a pipe passing through the upper portion thereof and projected into the lower end thereof, the said pipe being connected to the eaves-trough pipe, and having an opening'in the lower side of the portion lying within the casing, the said opening being closed by a wire mesh, of an upper vessel adapted to receive water through said wire mesh, a lower vessel adapted to receive water from said upper vessel in diminished quantity, pivotal arms, the said lower vessel, and a gravity-weight suspended from opposite ends of said arms, a separating-cylinder with which the lower end of the pipe communicates, the said cylinder having an unobstructed opening in one side adapted to discharge into the waste-pipe, and an opening in the opposite side covered with wire meshing and adapted to discharge into the cisternpipe, a connection between said cylinder and one of the arms, whereby said cylinder is 10 maintained in one or the other position by the
